 | Hello,
Anyone knows how to convert HTML strings in XML in Delphi? Any suggestions
for a good component to do this?
Thanks,
Victor

You can't really progmatically do it because HTML is so,
let me say, unstructured.
I'd suggest doing it manually by first using the
XHTML validator on W3c.org

The only good way I know of is to use the Tidy COM component. There is
also a parser called TagSoup which is written in C, I am not sure if
there is a way to get it into Delphi easily though.

I'm surprised that there are no good components to do this, there are a
couple of good one that we can use in Java and .Net. There's gotta be one
for Delphi :) I'll continue to dig around.
I'm thinking since IE does this by creating the DOM I wonder if we can
leverage IE to do this?
Regards,
Victor

I found this: http://www.elsdoerfer.net/delphi/?page=libtidy, makes it
really easy to use it from Delphi. There is an option to spit out XML from
Tidy. Works perfectly :)

Victor, with the plethora of crappy html on the web, it would
be close to impossible to do this correctly just from using the
IE DOM. Even Tidy has problem converting faulty HTML to XHTML.
Heck, even most HTML designers don't code XHTML well.
I think you could use something like the extIEParser from the
delphi-webbrowser Yahoo group to parse the HTML, it has events for each
type of tag, and "convert" the tag to XHTML in an in-memory copy of the
file.

Exactly how I'd do it with my parser..

It would make it a trivial operation.

I'm not an HTML designer by profession, but I do some
HTML and XHTML. My pages mostly validate. When they don't, it's not
because of the structure but for the content( which may be
custom ).
Do you mean "validates with W3C" by "code XTML well"?
Cheers,
Andrew

Well, I would say, yes, but you have to remember that there are several
DTD's to use with XHTML and you must validate against the DTD included
in the document.

That goes without saying. Validation *must* take place against the DTD
used in the document. I'm not aware of different validation kinds.

In recent days I've found and used a good HTML DOM implementation,
which I use to extract TEXT code from HTML files and create an
index dbase of words.
Try it on:
http://sourceforge.net/projects/htmlp/
Good enjoy...
PS:
There are also other good tools but don't have sources
without pay....

| Hi Victor,
You might consider using libxml2, which implements an HTML 4.0
non-verifying parser with an API compatible with the XML parser ones.
You can obtain libxml2 as a Windows binary from
http://www.zlatkovic.com/libxml.en.html
Delphi bindings for the DLL can be found at
http://sourceforge.net/projects/libxml2-pas/
(Note: I hope to provide an updated version of the Delphi bindings shortly.)
IMHO, the libxml2 parser is absolutely outstanding. It is very fast
(with my data, I find it to be about twice as fast as Microsoft's
parser), and is very convenient for cross-platform or cross-language
support.
